"Changed in version 3.8: The force argument was added." I think it's a better choice for new version.

From the source code of logging I found the flows:

This function does nothing if the root logger already has handlers

configured. It is a convenience method intended for use by simple scripts
to do one-shot configuration of the logging package.

So, if some module we import called the basicConfig() method before us, our call will do nothing.

A solution I found can work is that you can reload logging before your own calling to basicConfig(), such as

def init_logger(*, fn=None):

    # !!! here
    from imp import reload # python 2.x don't need to import reload, use it directly
    reload(logging)

    logging_params = {
        'level': logging.INFO,
        'format': '%(asctime)s__[%(levelname)s, %(module)s.%(funcName)s](%(name)s)__[L%(lineno)d] %(message)s',
    }

    if fn is not None:
        logging_params['filename'] = fn

    logging.basicConfig(**logging_params)
    logging.error('init basic configure of logging success')
